ABSTRACT:
A system and method for using licensed radio technology for determining the operation parameters which should be used by a terminal. The present invention involves the terminal using its GSM system, if activated, to determine whether mobile country code for a nearby cellular terminal is located within the United States or Canada. If the code designates the United States or Canada, then the terminal uses the US domain and the corresponding transmission channels and power levels. If the code does not designate the United State or Canada, then an ETSI domain is used, along with the appropriate transmission channels and power levels.
